When two boats share the same hull type — in this case both the Bayliner 170 Bowrider 2013 and the Bayliner 245 Cruiser 2009 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Bayliner 245 Cruiser 2009 measures 25,1 feet overall (2009), giving it roughly 7,6 additional feet of deck space compared to the Bayliner 170 Bowrider 2013 at 17,5 feet (2013). Weight tells a clearer story for trailering families: the Bayliner 245 Cruiser 2009 tips the scales at 6 144 lbs — 4 391 lbs less than the Bayliner 170 Bowrider 2013 at 1 753 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The Bayliner 245 Cruiser 2009 tops out at 300 hp. Engine specs for the Bayliner 170 Bowrider 2013 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Bayliner 170 Bowrider 2013 carries 21 gallons versus 7 gallons in the Bayliner 245 Cruiser 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Bayliner 245 Cruiser 2009 is rated for 8 passengers, while the Bayliner 170 Bowrider 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 245 Cruiser 2009 could be the deciding factor.
